35, 36 and 37 St Mary's Butts

A pair of buildings dating from the 16th or 17th century, substantially remodelled in the 20th century.

The buildings are constructed of brick and timber frame with a 20th-century brick glazed shop front on a brick plinth and plain tiled roof. The historic plan is obscured at ground floor level, having been opened up into a single shop unit, but originally both buildings would have contained two rooms to each floor with back-to-back rear wings. A part-attic storey exists over the wings and a basement extends beneath most of the building.

The exterior comprises two storeys with basement and part-attic. The principal front features a late 20th-century shop front on a brick plinth at ground floor level, with an off-centre late 20th-century entrance door to the shop and an additional late 20th-century door at the far left, providing access to the offices of number 36 above. Number 37 displays a bead-moulded jetty bresummer and jetty joists exposed at the soffit, with no evidence of a jetty plate (presumably replaced by the later shopfront, though it may be masked by the fascia). Above this is close-studded timber framing with midrails, an exposed wall plate and posts at each end of the jetty. Two modern two-light leaded casement windows are present, probably not in their original positions. Number 35 has an entirely late 20th-century appearance with a modern shop front and a three-light window in a brick surround to the first floor. The eaves have been cut back slightly. Both numbers 35 and 37 share a gable roof with irregular profile covered in plain tiles.

To the rear, exposed sections of box framing are visible, some rendered or clad with modern materials particularly at number 37. A substantial shouldered and truncated brick stack in red brick laid in English bond stands at the rear of number 35. Between the side elevation of number 35's rear wing and The Horn Inn to the south is a part-covered passage; the exposed elevations reveal box framing with brick panels laid in stretcher bond, storey posts and a midrail. Some repaired brickwork is apparent alongside narrow handmade bricks. Twentieth-century openings exist at the rear and side elevations.

The basement contains brick paviours and predominantly exposed brick walls, though some are rendered or overpainted. The front wall is constructed from narrow handmade dark red bricks in an irregular bond appearing to be a variant of English bond. An unusual curved passageway leads to the rear of number 35.

The ground floor displays 20th-century features and finishes with round columns supporting the jetty of number 37. At the rear of number 35's rear wing is an open fireplace with timber bresummer. The location of the original stairs is unclear, but a narrow 20th-century stair leads from the far-left entrance door to the first floor (number 36), where tie beams in the ceiling mark the former cross-walls above number 35. The wall plate to the façade is overpainted but evident, though the wall frames are not exposed. The cross-wall between numbers 35 and 37 is partly in situ, with a substantial tie beam, wall post and storey post remaining, along with some exposed ceiling joists. The northernmost room contains exposed pegged timber framing of substantial scantling, including a jowled storey post and a cranked corner brace at the north-east corner jointed to a tie beam. Some wall framing is of lighter scantling, particularly to the front wall, and is probably later in date, but the wall plate and bottom of the common rafter roof structure are exposed. The cross-wall to the south is similar in form with a substantial tie beam, close studding and straight bracing. This room contains two 18th-century two-panel doors with HL hinges. The door leading into the rear of number 35 retains part of a moulded architrave with a modern fillet.

The attic contained no exposed historic fabric and the upper part of the roof structure was inaccessible.
